Lead to Lithium

Hi all. Thanks for all the replies on my busted amp and the DAT battery hack.
Yesterday, I went and bought several NiCd batteries and wired them in series in the
original batery seal for a perfect Fit (I was kind of proud of myself).
Of cource this was before I got replies from Peter Blackett and Hugo (which I just got).
Both told me this would not be that simple (especially if I was changing batery types ie:
lead to lithium) because I would need a different way to charge it. Well, sure enough,
night the batteries worked for a couple of minutes real well (I guess the batteries were
somewhat charged) but I have not been able to rehcarge them. And, I don´t think I want
to keep trying anymore (don´t want to mess up the DAT).
So here is my next question. How can I make a simple charger for NiCd cells from the
original 7.4 volt supply. Is it a better idea to buy a charger?
THe pack I made is not very robust, I supose about 400mAH, I´m just guessing here. But
at the store there was a really nice pack (large): NiCd 6V 4.5 AH. So If I could make or
buy a charger to charge my home made pack and the larger one, I would be set. THe
larger one for long hours, and the smaller one for more portability.
On Barry Klein's I read there are different ways of building chargers: current limiting
resistor, voltage regulator, intelligent voltage something or other. Which do I need for
NiCd? And, isn't the wall wart voltage regulated?
By the way Hugo, since you have the same DAT I do , do you know if I can still get those
batteries (it would be a good Idea to get the original replacement, but I did not find it
their web sites havfe you replaced yours ever?
THANX AGAIN ALL
